`This invention relates to an improved form of inking roller for use in`connection jwith check-endorsing machines and the like. A

is is Well-known to those who are familiar with the .art to whichthe'present` invention relates,.there are devices'of this general typein which inl; is applied to thev inlring roller from time to time lfromtheoutside and'by' hand. l his process is quite laborious and inrolvesthe loss of time which might be saved by the employment of suoli adevice as here set forth. A Y

.ln other instances, it has been proposed to maintain the inlringrollervconstantly full of .i lul: which yfinds its Way yout throughperforations in the drum of thelinking roller. This ty )e of device isalso open to objection since there is danger of the ink being fed tooplentifully to the felt covering of the in lrin'g roller 1.- u'ithconsequent blurring and furthermore,

vention to devise an inlring roller which may be supplied with inlr onlyto an extent commensurate With the use required during operation. Thatis, according to the present invention, the inlring roller does notconta-in any supply of ink except that Which is con# stantly fed theretoduring operation and ac cording to the actual need.

Another object consists `in providing such a device With means wherebythe ink may be supplied only as required for use during operation, andat the same time7 may be automatically fed from the inside oftheperforated drum of the inking roller to the outside thereof bycentrifugal action. v

A still further object consists in the provision of such a device invwhich a standard type of ink reservoir maybe employed forfe-eding theink to the inking yroller according to the immediate need duringoperation. Otherobjectswill appear from the 'following descriptionandclairns when considered together With the accompanyingdravving. Fig.l is aV diagrammatic plan view illus-` trating the installation of mypresent form' of device in a check-endorsing machine ;V Fig. 2 is adetail view taken on line 2--2 of l; and Fig. 3 is another detail Viewtaken on line 3-3 of 2. 'i

The Structure and arrangement of the parts comprised in the Well-knownform of check? endorsing machine are hereillustrated onlyv in a generalWay7 asmay'be necessary to illustrate the relative arrangement of thepresent improved inlring roller with respect to the other partsof thecheck-endorsing machine. This type of machine comprises the table 1 uponthe upper side of which are arranger the Vseries of rollers for feedingthe checks for the endorsing operation. These rollers are operated inpairs and are all positively driven from a motor arranged upon theunder' side ofthe table l. The roller whichA carries the die forendorsing the check is indicated -by reference numeral 2 and the presserroller associated therewith is indica-ted by reference numeral 3. Thedie roller islilre- Wise positively driven from the motor. The inkingroller is indicated in a general Way in Fig. l by reference numeral 4and is supported by a bracket 5 Whichhas detachable engagement upon thetableV 1 byfvmeansof any suitable attachment, as for instance, the Wingnut 6 engaging the slot 7 in the bracket arm 5. Any suitable means maybe'further employed for maintaining the bracket arm 5 in proper fixedposition. It is understood that the inking yroller l engages the dieroller 2 so Vas to supply inl; thereto. roller t is freely mounted forrotation by engagement With'the die roller 2 and-is not positivelydriven from the motor which drives the other rollers. Y

Those who are familiar `With this type of machine will understand thatall of the rollers herein referred to are mounted for rotation uponvertically disposed axes and that the checks are fed therethrough in verical The inking ing to the present invention, the rate of feeding of theink to the inlring roller may be varied accordingly.

In the present device, there is employed the usual form of ink reservoirS'Wliich con'- 10 art.

" bracket arm 5. The bracket receive the cover 12.

sists of a glass container Well known in the This yreservoir is mounteduponthe angular form of bracket 9 which is clamped by means of the boltand screw 10 to the: l 9 is so arranged as to position the inlrreservoir8V directly above the inlring roller l for Isupplying the ink thereto.The ink from the reservoir 8 is adapted to be fed drop bydrop throughthe depending tube 11 Which extends through an opening in the removabletop 12fcf the inkng roller. rlhe tube 11 is positionedoffcenter withlrespect to the anis of the inlring roller for a reason to be laterexplained. The inking roller comprises the perforated cylindrical drum13 Which is closed at its lovver end and'which has an open upper end torlhis drum is provided with the hollow bushing 1d for mounting upontheuprig'ht stein 15 provided upon the horizontal bracket 5. rEhe stein15 is :of cylindrical form throughout its'entire eX- tent so as. topermit rotation of the inling roller thereuponexcept that the upper endportion ofthe stem 175 above the inking rol-ler is of squared form so asto -receive the squared centralV opening Athrough the cover 12. ,A pin16 extends through an opening in the squared portion ofthe stein 15 soas to prevent accidental reinovalof the cover 12. v drum 13 is providedwith a felt cover-ing 17 which is kadapt-ed to receive the ink throughthe openings in the drum 13 from the insidel thereof.

Depending from the under side of the cover 12, there is provided alinger 18 which attached to the cover at a pointed-center and extendsangularly in a substantially curved form toward the bottom corner of thedrum This member is 4so constructed and arranged as to extend under thetub-ular member 11 so as to receive the inl; as it drops therefrom. Theouter edge of the finger 18 is sufficiently close tothe side wall of thedrum 13 to transfer a por-tion `of .the ink received thereby to theinner surface of the drum. The remaining portion of the inl: drops fromthe inner edge of the linger 18, is picked up by the bot-tom end of thefinger, and the rotary movement of the drum will cause this ink to becarried up the linger and distributed from the outer .edge of the fingerto the inner surface .of the drinn. The lower end ofthe linger 18 isvery'close ,to the bottom of the drum and there is ensured a supply ofink to the entire surface .of the drum during operation of the device.According to the present invention, the rotary' motion of the drum 13 isdepended upon to carry the ink, as it is received upon and distributedby the nger 18, upwardly over the inner surface of the drum 13 so as toform a film of ink entirely thereover.

During periods of idleness, the supply of ink fromthe reservoir 8 is cutolf so that no ink'vvhat'ever is fed to the inside of the inking roller.`When it is desired to operate the check-endorsing machine, the inksupply from -thereservoir 8 is opened so as to feed the ink to theinside of the drum. During this time, l

the ink will be fed drop by drop from the lower end of Vthe tube 11 andreceived upon the'` finger 18 Which-transfers p a-rt of the ink directlyto the inside ofthe drum 13, While the other part of the ink is p idkedup by the finger and transferred to the drum. Rotation of the drum 13Will cause uthe ink Which is supplied in such manner to be spread asV afilm over the entiresurface .of the drum and as a result, Ithe.inlravill be fed to all parts of the drum, As beforestated, the ink issupplied 'onlyat a rate of speed corresponding approximately to theimmediate requirements of the machine during its operation. As a result,the inl; is not permitted Yto accumulate in the drum to any appreciabledepth, but is supplied only according to the rate of use. In otherWords, the vink is .transferred through the openings of the drum13 tothe felt covering 17 at s ubstantially the same rate of speed as it isfedto the drum.

As an advantage of the present invention, the ink is su pliedautomatically to .the ink- Y ing roller an consequently it is notnecessary to ink the roller from the outside, as has been the custom vincertain machines of this same A With this device, all portions of thefelt covering 17 are supplied with ink in the same uniform manner andconsequently, the impression of the endorsement presents a .uniformVappearance throughout. The present device maybe readily lattachedto thepresent form of check-endorsing machine Without involving the -change ofany other parts, .and also the standard form of ink reservoir may beemployed for feeding the ink to the inking roller. Hence, the presentform of device may be manufactured and soldl at l.comparatively lowcost.p

Because of the absence of perforations in the lowermost part of the drum13, as clearly indicated Fig. 2, there is no danger .of any film @t ink:in the bottom Seepng outthrough the drum eine Covering/i eine -iiiedevice is idle.
